Whereabouts in Oz are you? There are a few dingos on this forum and they may be able to direct you to a local piercer.
There is nothing wrong with the position you have chosen, like @Kinanizer said, MOST people get their first implant in position #0 aka (between thumb and forefinger, Thenar space, between the 1st and 2nd metacarpal) and have no issues with wall readers, minimal contortion required, but yes, the position you chose would be slightly easier to use, but also slightly more difficult to install. Either way not exactly arduous.
FYI, have a read of the below, It is forum specific, so the numbering won’t mean anything to a piercer you approach, but for your reference…
